Chapter 4 Last, but Not Least 51
Important: The power adapter for your computer is a high-voltage component and
should not be opened for any reason, even when it’s unplugged. Do not allow children
access to the interior of any electrical product and do not permit them to handle any
power cables. If the power adapter needs service, see the service and support
information in “Learning More, Service, and Support” on page 41.
Laser Information
Do not attempt to disassemble the cabinet containing the laser. The laser beam used in
this product is harmful to the eyes. The use of optical instruments, such as magnifying
lenses, with this product increases the potential hazard to your eyes. For your safety,
have this equipment serviced only by an Apple Authorized Service Provider.
Because of the optical disc drive in your computer, your computer is a Class 1
laser product.
WARNING: Use only the power adapter that came with your computer and the AC
cord that came with your power adapter. Adapters and cords for other electronic
devices may look similar, but using them may affect your computer’s performance or
damage your computer. The AC power cord has a three-wire grounding plug (a plug
that has a third grounding pin) that will fit only a grounded AC outlet. If you are
unable to insert the plug into an outlet because the outlet is not grounded, contact a
licensed electrician to replace the outlet with a properly grounded outlet.
